摘要
Abstract
The static adsorption and selective water shutoff performance of a cationic polymer type relative permeability modi-fier(RPM)were studied. The results show that the static adsorptions of RPM on quartz sands and oil sands are both langmuir adsorption,and the adsorption on quartz sands is twice of that on oil sands;the static adsorption is strongly affected by electro-static attraction and the wettability of solid surface,and RPM can alter the oil wet surface(105°)to weakly water wet(72°);core flood tests are conducted to study the selective water shutoff of RPM,and it shows that the oil and water residual resis-tance factors decreases with the increase of permeability,temperature and brine salinity. The swelling/shrinking of polymer adsorption layer is a reasonable explanation for RPM selective water control.关键词
